I need a finished module consisting of an Arduino nano and SIM800(x) GSM. The system should be able to write SMS and make calls via functions. Later a 3,7V (4,2V) 1 cell Lipo with step-up converter will be used as power supply. The best way is to connect the two components via pin headers in order to be able to replace them easily. No need to have a mic or speaker.
What needs to be done?

You will be making two designs. One for the SY8089 and one for the MP2161.
You will need to select the most suitable components (resistors, capacitors, inductors etc) to achieve the desired results. You will need to provide a circuit diagram and a PCB design. You will need to show the formula that you used to determine the value of each component. I will manufacture the PCB that you design to test...

Hello,
I hope you are well.
I am looking at designing a new Agricultural Spraying Drone for industrial use. I have been looking at suppliers in china which already make some of these but I want to re-design the look and add features to the flight controller etc.
I am in need of help with someone that can help me with the design, Components (Motors, Flight controllers, GPS, Imaging, Spraying et...

I have produced conceptual model diagram for each of the units of Wireless Alarm System along with detailed explanation text of the project.
I want a complete logical diagram and PCB layout diagram to be produced.
I am also happy to receive any alternative approach.

I would like a PCB board(s) design so that I can complete this project. I have made an 8x8x8 LED RGB cube, I have a schematic which I have attached and was created using Eagle, however I am not fussed if you need to use a different program as long as I can send the files off to print the PCB.
I will tell you this was not my plan and I got this idea from this web site [iniciar sesión para v...

to do this project, you need to have
(1) one Raspberry Pi (Master) device, and one nrf24l01+ device is on Raspberry Pi.
(2) many Arduino devices (slaves), and each Arduino device has one nrf24L01+ device.
Master will send a "syn" signal to all slaves, every 1 or 2 seconds, to ask all slaves to do a measurement. All slaves shall receive a "syn" signal from Master every 1 to 2...

This session involves establishing familiarity with a wideband means of modulation, Code Division Multiple Access (CDMA). Numerical processing tools are utilised to explore the physical layer signalling associated with CDMA.
This session will be done in MATLAB. I'm looking for MATLAB code and explanation with each step to be followed by notes provided.

We have a design that we want to redraw for Altium. It's a signal amplifier with resistors, capacitors and OAMP'S. The project is well documented, and detailed SCH will be distributed in PDF, BOM in EXCEL and Gerber for top and bottom as digital files.
The attachment shows one drawing of 3.

We have a kicad rat's nest with all the connections made. We would like to have the high speed digital board laid out and work the first time. If you are really good at high speed digital design including lpddr and wifi we would like to talk to you.

We need an electrical engineering firm to do a MTBF calculation on our electrical design. We have a complete BOM that need to be completed into a real time life expectancy assuming all components are operating within the recommended manufacturers design parameters.

Processor - AM335x
Codec - TLV320AIC3106
Project involves 8 devices connected in a network. Out of 8 one will be the master and rest are slave devices.
There are two operating modes.
1. Unicast - Cross talk between Master and slave.
2. Broadcast - Master will announce and slave will receive only

I need a single input n output automatic switch block in Simulink. by saying Automatic I mean:

1st clock cycle: the first input sample will go to first output.
2nd clock cycle: second input sample will go to second output.
3rd clock cycle: third input sample will go to third output.
4th clock cycle: the fourth input sample will g...
